Vulnerability Assessment

Weakness	CWE CWE-74 OWASP Top 10:2025 A05:2025 - Injection ASVS 5.0 V1 - Encoding and Sanitization Input neutralization, injection prevention
Exploitation Conditions	The logout.php endpoint is reachable without authentication and directly processes the 'uname' parameter without sanitization. Exploitation requires no user interaction and no special privileges; the default deployment of Simple Stock System 1.0 is vulnerable.
Impact	CVSS 4.0 vector (AV:N/AC:L/PR:N/UI:N, VC:L/VI:L/VA:L) scores 5.5 (Medium), indicating easy network exploitation but limited impact. EPSS is 0.05% (15th percentile), suggesting low likelihood of widespread exploitation. No KEV listing means no observed active attack campaigns. Public PoC lowers the barrier, but the niche product footprint keeps risk moderate. Overall, a low-priority vulnerability for most organizations unless this specific software is in use.
Exploit ScenarioDerived	An attacker sends a crafted HTTP request to /logout.php containing SQL payloads in the 'uname' field, which is then executed by the application's database. This could allow dumping usernames, modifying passwords, or bypassing logout functionality to maintain session access.

This Month Plan within 30 days. Why: MEDIUM severity (CVSS 4.0-6.9).

AnalysisAIv1 – Jul 26, 2026

SQL injection in Simple Stock System 1.0 allows remote attackers to manipulate the uname parameter in /logout.php, potentially bypassing authentication or altering backend data. Public exploit code is available, though no active exploitation has been reported.

RemediationAI

No official vendor patch has been identified. Apply input validation or parameterized queries to the 'uname' parameter in logout.php. As a temporary workaround, restrict network access to the application or deploy a WAF rule to block SQL injection patterns targeting logout.php. Consider migrating away from this unmaintained project.
